What is the slope of the line that is perpendicular to the line that passes through (-2, 7) and (4, 9)? Type a numerical answer

kodGreya [7K]

Answer:

Therefore $m_{2}$ = -3.

Step-by-step explanation:

i) let us say the slope of the line passing through (-2,7) and (4,9) is $m_{1}$ .

ii) to find the slope of the line passing through two points ( $x_{1}$ , $y_{1}$ ) and ( $x_{2}$ , $y_{2}$ ) we use the formula m = $\dfrac{y_{2} - y_{1} }{x_{2} - x_{1} }$ . Therefore we can say that $m_{1}$ = $\dfrac{9 - 7}{4 - (-2)}$ = $\dfrac{1}{3}$ .

iii) let us say the slope of the perpendicular line to the line passing through (-2,7) and (4,9) is $m_{2}$

iv) from the formula for the slopes of a line and the line perpendicular to it which is given by $m_{1}$ × $m_{2}$ = -1, therefore $m_{2}$ = -1 ÷ $m_{1}$ = -3. Therefore $m_{2}$ = -3

Point slope form and standard form

SVEN [57.7K]

The point slope form, , is useful in situations involving slope and the location of one or more points. The standard form, , is usually easier to use when we need to make algebraic calculations. When needs or knowledge change, we can convert an equation from one form into another.

Please help me .....

Answer:

150 feet of flowers would be planted along side C

$a=5400$

Step-by-step explanation:

Use the pythagorean theorem to find the length of side C

$a^2+b^2=c^2$

Input the corresponding numbers into the formula

$90^2+120^2=c^2$

$c^2=22500$

$c = \sqrt{22500} \\ c=150$

150 feet of flowers would be planted along side C

To find the area multiply the base and height together, and divide the total by two

$a = \frac{bh}{2}$

$a = \frac{90 * 120}{2} \\ a=5400$

3 years ago a father was 3 times as old as his son in 5 years time he will be twice as old as his son in, what will be the sum o

Troyanec [42]

46 because if the age of the son was 8 then the father was 24 and if we add 8 (because that’s how many years passed) we get 16 and 32 which fit the criteria so if we take off 1 year on each (because only 7 years pass instead of 8) we can add them together and get 46
